yii2 ActiveRecord通過計算查找OrderBy

Question

嘗試從我的數據庫中獲取描述。 查詢返回結果，但我想命令結果只顯示投票率最高的結果。

投票應通過downvoted列減去的upvoted列計算

$description = UnitDescription::find()
   ->where(['id_unit' => $model->id])
   ->orderBy([
      'upvoted - downvoted' => SORT_DESC //Need this line to be fixed
   ])
   ->one();

我希望有人可能有辦法寫這部分查詢 - 謝謝

Answer 1

你應該嘗試：

$description = UnitDescription::find()
    ->where(['id_unit' => $model->id])
    ->orderBy(['(upvoted - downvoted)' => SORT_DESC])
    ->one();
